摘　　要：高铁路基沉降组合预测研究取得了一定成果,但有关理论和流程仍不清晰,在梳理常用单项预测法适用性的同时,对高铁路基沉降评估指标进行了归纳总结,定性和定量分析了组合预测模型筛选策略;围绕并联式组合预测权重和最终沉降量的确定展开评述;应用工程实例展现了整套流程。以期为预测评估工作提供科学化、系统化、标准化的依据。Some achievements have been made in the combined prediction of high railway foundation settlement,but the related theory and process are still unclear. In reviewing the applicability of common single prediction methods at the same time, the evaluation indexes of high railway foundation settlement are summarized. The selection strategies of combined prediction models are analyzed qualitatively and quantitatively, and then the determination of the weight of combined prediction and the final settlement amount is reviewed. A project example is used to show the whole process in order to provide scientific, systematic and standardized basis for prediction and evaluation.
